Revert "kernfs: remove KERNFS_REMOVED"
This reverts commit ae34372eb8408b3d07e870f1939f99007a730d28.

I'm sorry but can you please revert the whole series?
get_active() waiting while a node is deactivated has potential
to lead to deadlock and that deactivate/reactivate interface is
something fundamentally flawed and that cgroup will have to work
with the remove_self() like everybody else. IOW, I think the
first posting was correct.
